When historians write of the world’s recent history, they are likely to reflect on two trends: the advance of globalization and the spread of democracy. Globalization has been the more contentious, because it has effects both good and bad, and democracy has opened space for people to protest the bad effects.

For many people this new diversity is exciting, even empowering, but for some it is disquieting and disempowering.
